Designing Active-Clamp Forward Converters Using Peak-Current-Mode Controllers By: K S Bhanuprasad Aug 05, 2014, Maxim Integrated Products, Inc. Abstract: Active-Clamp Forward converter design using MAX17598/MAX17599 is outlined. Design methodology and calculations for components value selection are presented. Introduction This APPLICATION note describes the methodology of Designing Active-Clamp Forward converters using the MAX17598/MAX17599 peak-current-mode controllers.
The maximum operating duty cycle (D MAX) is chosen to be less than the absolute maximum duty cycle of the MAX17598/MAX17599 ICs (72.5%, typical). Transformer turns ratio, DCMIN MAX OUT V D V k × = where D MAX (63%, typical) is the assumed maximum duty cycle at minimum input voltage Minimum duty cycle at maximum input voltage can be calculated ...
